Abstract
The utility model discloses a vacuum pump improves structure for promoting vacuum, including the vacuum pump body, be equipped with the water inlet on the vacuum pump body, the water inlet is equipped with the valve that control rivers were stopped through hose and the inlet tube intercommunication that the diameter is 0.8-1.2cm on the inlet tube. This a vacuum pump for promoting vacuum improves structure and changes the water inlet structure of vacuum pump for solve the not enough defect of vacuum among the prior art.
Description
The technical field is as follows:
the utility model relates to a vacuum pump improves structure for promoting vacuum.
Background art:
currently, a vacuum pump is a device or apparatus that uses mechanical, physical, chemical or physicochemical methods to pump a container to obtain a vacuum. The rotary variable-capacity vacuum pump needs to be matched with a backing pump, can be used in a wider pressure range, has larger pumping speed, is insensitive to dust and water vapor in the pumped gas, and is widely applied to the industries of metallurgy, chemical industry, food, electronic coating and the like. Among them, the water-ring vacuum pump is the most common one of the liquid-ring vacuum pumps. The liquid ring vacuum pump is a rotor with multiple vanes eccentrically arranged in a pump shell. When it rotates, it throws the liquid toward the pump shell and forms a liquid ring concentric with the pump shell, and the liquid ring and the rotor blades form a rotary variable-volume vacuum pump with periodically-changed volume. When the working liquid is water, the water ring pump is called. The performance of the product can basically meet the production operation of common products, but the product has the disadvantages of low efficiency, generally about 30 percent and better reaching 50 percent; secondly, the vacuum degree is low, because an iron pipe with the size of 6 centimeters is connected with a water inlet of the vacuum pump, the water consumption of the pump does not need to be too large, and the water is discharged from a general valve to a drain valve, so that air in a main water pipe connected with the iron pipe enters, the vacuum degree cannot meet the requirement, and a certain difference exists in the technical requirement of the anti-yellowing fatty amine polyoxyethylene ether.
The utility model has the following contents:
the utility model aims to solve the technical problem that a change water inlet structure of vacuum pump is provided for the vacuum pump that is used for promoting vacuum of the not enough defect of vacuum among the solution prior art improves the structure.
The technical solution of the utility model is that, a vacuum pump improves structure for promoting vacuum is provided, including the vacuum pump body, be equipped with the water inlet on the vacuum pump body, the water inlet is equipped with the valve that the control water circulation ends on the inlet tube through hose and the inlet tube intercommunication that the diameter is 0.8-1.2 cm.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: through the mode of repacking stereoplasm inlet channel into tiny hose, realize improving the function of vacuum, the extreme pressure 8 ~ 2 x 103Pa of single-stage water ring pump has been brought into play extremely well, vacuum has reached minus 0.110, get off like this and have great promotion to the performance of product, and simultaneously, because there is not spot welding seal structure, there is not the metal friction surface in the pump chamber, need not lubricate in the pump, it can directly be accomplished by the water seal to rotate between piece and the mounting, the sealing performance has been strengthened, the life of vacuum pump has been improved.
Preferably, two ends of the hose are respectively connected with the water inlet and the water inlet pipe of the vacuum pump body through quick connectors. The connection is convenient.
Further, the hose is a plastic hose.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in figure 1, a vacuum pump improves structure for promoting vacuum, including vacuum pump body 1, is equipped with water inlet 11 and delivery port 12 on the vacuum pump body 1, and water inlet 11 is through diameter 1 cm's hose 2 and inlet tube 3 intercommunication, the external tap water pipeline of inlet tube, is equipped with the valve 4 that the control rivers were stopped on the inlet tube 3, and delivery port 12 in use is unanimous with prior art, is connected with the buffer tank through the pipeline. And, hose 2 both ends are connected with the water inlet 11 and the inlet tube 3 of vacuum pump body through quick-operation joint 5 respectively, and quick-operation joint 5 is fixed with water inlet and inlet tube spiro union, and quick connector is inserted respectively at the both ends of hose, is used as the inlet channel, and hose 2 is the plastic hose.
When the single-stage water ring pump is used, the pump is started firstly, then the water is boiled, so that the water pipe is prevented from falling off, the pump is stopped and is required to be turned off firstly, so that the limit pressure of the single-stage water ring pump is 8-2 multiplied by 103Pa to be exerted to the utmost extent, the vacuum degree reaches minus 0.110, and the technical requirement of the anti-yellowing fatty amine polyoxyethylene ether is completely met. Meanwhile, no metal friction surface exists in the pump cavity, and the interior of the pump does not need to be lubricated. The sealing between the rotating part and the fixing part can be directly completed by a water seal, so that the sealing performance is improved, and the service life of the vacuum pump is prolonged. In addition, the gaseous process temperature variation of pump chamber internal compression is very little, can regard as isothermal compression, the utility model discloses can easily take out inflammable, explosive gas, the production of resistance yellowing fatty amine polyoxyethylene ether is protected and is driven the protection navigation. Meanwhile, as the water pipe is reformed, the water consumption is much less, which is beneficial to energy conservation and environmental protection.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
